My Mazda 3 started getting the classic i-Stop error message and I am thinking of replacing my battery with a 3rd party, maintenance free type.
I know that it should be a Q85 type, however what's the best option in terms of durability, performance and price?

 

At my dealership we use AC Delco QA85 batteries. They have a good reputation and are well priced.

 

Thanks, I'll have a look on those. How long do they usually last?
